Hey Simon.
Basically you put together a group of 3 drivers – they can all be in different cars and classes – and you have a team. Your times are added together and obviously the lower the overall time the better. Simple as that really! It's a bit of a fun extra.
"Team Pdiddy" or "GC8 McLovin" are possibilities
From the supregs:
"Team entries will be accepted on the day of the event up until 9.30 am. A team must comprise of three (3) drivers, submitted on a club basis and consist of at least two (2) vehicles. Multiple team entries by the same driver are not permissible. The team name and members should preferably remain the same for all rounds of the Championship as points are allocated on the basis of the team name. However it may be permissible to substitute up to three drivers over the Championship series."
